- Brief summaryGraves’ ophthalmopathy (GO), or Graves Orbitopathy, is clinically present in ~25% of patients with Graves’ disease (hyperthyroidism). There is consensus that patients with active, moderate-to-severe GO qualify for immunosuppression: weekly pulses of intravenous methylprednisolone for 12 weeks are recommended. However, because of disappointing response rates to prednisolone, alternative treatments with similar efficacy but less side effects would be welcome, not only in patients in whom steroids are contraindicated. A number of studies, have demonstrated that octreotide and lanreotide do not improve or marginally improve eye changes as compared to placebo despite the fact the orbital fibroblast expresses the somatostatin receptor. The cause of these disappointing results could well be the low affinity of octreotide and lanreotide for all somatostatin receptors except subtype sst2, whereas in GO a clear up regulation of sst1 and sst5 on OF has been observed. Pasireotide (SOM230) indeed has a greater inhibitory effect on in vitro proliferation of orbital fibroblasts than octreotide, and both pasireotide and octreotide inhibit human lymphocyte proliferation albeit acting at different concentrations.
Result of a recent trial that we have performed showed disappointing results when moderate to severe GO patients were treated with intravenous prednisolone with improvement of a predefined response criterium in only ~50% of cases. Previous studies showed higher response rates, which may have been due to the fact that in these early studies patients with more severe GO were included. However, the response to intravenous prednisolone underscores the need of additional therapies.
Therefore, we aim to investigate in a pilot trial the effect of SOM230 on predefined endpoints in patients with moderate to severe GO whom have contraindications for prednisolone therapy or decline from prednisolone therapy for other reasons.
